Take pistachia, eringoes, of each half an ounce; saffron, one drachm; lignum aloes, galengal, mace, coriophilla, balm flowers, red and white behen, of each four scruples; syrup of confected ginger, twelve ounces; white sugar, six ounces, decoct all these in twelve ounces of balm water, and stir them well together; then put in it musk and amber, of each a scruple; take thereof the quantity of a nutmeg three times a day; in the morning, an hour before noon and an hour after supper. But if the cause of barrenness, either in man or woman, be through scarcity or diminution of the natural seed, then such things are to be taken as do increase the seed, and incite to stir up to venery, and further conception; which I shall here set down, and then conclude the chapter concerning barrenness. For this, yellow rape seed baked in bread is very good; also young, fat flesh, not too much salted; also saffron, the tails of stincus, and long pepper prepared in wine. But let such persons eschew all sour, sharp, doughy and slimy meats, long sleep after meat, surfeiting and drunkenness, and so much as they can, keep themselves from sorrow, grief, vexation and anxious care. These things following increase the natural seed, stir up the venery and recover the seed again when it is lost, viz., eggs, milk, rice, boiled in milk, sparrows' brains, flesh, bones and all; the stones and pizzles of bulls, bucks, rams and bears, also cocks' stones, lambs' stones, partridges', quails' and pheasants' eggs. And this is an undeniable aphorism, that whatever any creature is addicted unto, they move or incite the man or the woman that eats them, to the like, and therefore partridges, quails, sparrows, etc., being extremely addicted to venery, they work the same effect on those men and women that eat them. Also, take notice, that in what part of the body the faculty that you would strengthen, lies, take that same part of the body of another creature, in whom the faculty is strong, as a medicine. As for instance, the procreative faculty lies in the testicles; therefore, cocks' stones, lambs' stones, etc., are proper to stir up venery. I will also give you another general rule; all creatures that are fruitful being eaten, make them fruitful that eat them, as crabs, lobsters, prawns, pigeons, etc. The stones of a fox, dried and beaten to a powder, and a drachm taken in the morning in sheep's milk, and the stones of a boar taken in like manner, are very good. The heart of a male quail carried about a man, and the heart of a female quail carried about a woman, causes natural love and fruitfulness. Let them, also, that would increase their seed, eat and drink of the best, as much as they can; for _sine Cerere el Libero, friget Venus_, is an old proverb, which is, "without good meat and drink, Venus will be frozen to death."
